i have an obd2 swap thats im putting in my obd1 eg coupe... what do i need has far as any harnesses or componets to change to make it work.. i would appricate any advice n dont bash me its my first swap soo im learning little by little.. thanks

 

depends on what motor you're putting in.. and what model coupe u have...

 

bump...

 

Why are you bumping. He needs to answer the basic questions like what car is it and what OBD2 engine is. It will make a huge difference.

 

 

i have a b18c1 gsr and its going into a 94 civic coupe dx car as nothing power has a/c but its not staying

 

In that case run a '96 - '99 Integra engine harness if you can get your hands on one as it eliminates most of the wiring.

 

ok now i have the the engine harness that came with the engine now can i still use it for the swap

 

Yes.

 

ok soo jst for comfirmation the obd2 engine harness that i have i can use in my obd1 car and not have to change pins or any componets?

 

Yes.

 

you wont have to remove any pins just add vtec wires, knock sensor wires, and iab wires to your shock tower harness or make your own.

 

now my real question is could i just use a obd2 to obd1 jumper harness n just use a p28 ecu? would that save me from having to pin anything

 

i think what i am also failing to mention is that my eg coupe (dx) is not vtec soo there for i would have to run wires for vtec correct?

 

Yes U need to add vtec wires. No u dont need a obd2 to obd1 jumper to use a p28. Your car is already obd1

 

ok you know of where i can get the info to run the wires n which spot to put the pins etc... and thanks for the input i appricate it

 

p28 will not operate the IABs, so you won't need to wire that in

 

soo do i need to wire the iabs at all then?

 

keep ur d series harness... ull need to splice or get a jumper harness for ur dizzy, alternator, and maybe extend ur o2 and iat and wire up vtec, other then that ur set. don't worry about the ckp, obd1 doesn't need it to run, i just left it unplugged. run a p28 and ur set.

 

you don't have to run knock if u run a p28 either

 

Do not keep your stock dx harness. Your obd2 harness will plug right up to the three plugs at the shock tower. All you will need to do at that point is run vtec wires and knock from the shock tower to your ecu.please use the search function and or the FAQ at the top of this section most if not all of your questions will.
